Quelques soucis avec un disque SCSI.

Bonsoir la liste,
- J'ai un disque SCSI de 37GB qui me pose des soucis. J'ai une première question, lors du boot, le disque en question est très bien détecté, mais il y a ces messages que le noyau affiche au démarrage (syslog) : 

************* kernel: sd 1:0:2:0: SCSI error: return code = 0x00010000
************* kernel: end_request: I/O error, dev sdc, sector 8
************* kernel: Buffer I/O error on device sdc, logical block 4
************* kernel: Buffer I/O error on device sdc, logical block 5
************* kernel: Buffer I/O error on device sdc, logical block 6
************* kernel: Buffer I/O error on device sdc, logical block 7
************* kernel: Buffer I/O error on device sdc, logical block 8


Est-ce grave ? Est-ce que le disque est en fin de vie ?? Une solution ?
- Ensuite, lorsque je tente de formater via un cfdisk /dev/sdc ou fdisk /dev/sdc, impossible, ça se bloque, cfdisk ne s'ouvre pas, fdisk s'ouvre mais impossible de formater. 

- J'ai ensuite fait :

for DISK in a b c d ; do
fdisk /dev/sdc <<EOF
p
q
EOF
done

Et ça me renvoit :

The number of cylinders for this disk is set to 4492.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
  (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help):
Disk /dev/sdc: 36.9 GB, 36954401792 bytes
255 heads, 63 sectors/track, 4492 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

  Device Boot      Start         End      Blocks   Id  System

Unable to read /dev/sdc
Apparemment impossible d'accèder au disque, quelle solution faut-il envisager ? 

Merci pour votre aide,
